Answer
a. $LiCl$ is soluble in water.
b. $AgCl$ is insoluble in water.
c. $BaC{O_3}$ is insoluble in water.
d. $K_2O$ is soluble in water.
e. $Fe(N{O_3})_3$ is soluble in water.
Work Step by Step
a. Compounds with the $Li^+$ ion are soluble in water.
b. Compounds with the chloride ion $(Cl^-)$ are mostly soluble, but, $AgCl$ is an exception.
c. $Ba^{2+}$ and $C{O_3}^{2-}$ do not appear in the Table 9.7, so, $BaCO_3$ is insoluble.
d. Compounds with the $K^+$ ion are soluble in water.
e. Compounds with the $N{O_3}^-$ ion are soluble in water.
